O Mundo Aromático - dos PAHs no meio interestelar às condições bióticas
[thesis]
A considerable fraction of carbon in the interstellar medium -20% or more -is in the form of polycyclic aromatic hydrocarbons (PAHs), and their mid infrared emission lines are dominated by bands related to this class of molecules (Joblin et al., 1992). When a PAH incorporates one or more atoms of nitrogen, that substitute the carbon atoms, it becomes a polycyclic aromatic nitrogen heterocycle (PANH). They can provide the missing link between the abundant PAHs chemistry at the ISM and the
